If the screen edges are cut off, adjust screen fit or overscan settings.
Enable compatible HDR settings only when your display supports them.
Use a high-quality HDMI cable for 4K playback.

Navigate to Settings, then Display & Sound or Audio, depending on your system menu.

Use HDMI audio for standard TV sound.
Use optical output when connecting to a receiver or soundbar.

Restart the app after changing audio output if needed.

Tip: If sound is delayed, check whether your TV, receiver, or soundbar has an audio sync setting.

Remote not responding

Replace the batteries, move closer to the device, and check whether the remote needs to be paired again.

Wi-Fi drops frequently

Restart your router, use 5G Wi-Fi when close to the router, or connect Ethernet for the most stable setup.

App crashes or freezes

Close the app, clear its cache, restart the device, or reinstall the app from a trusted source.

4K content is not playing in 4K

Confirm that your TV supports 4K, use a compatible HDMI cable, choose a 4K display setting, and make sure your internet speed is strong enough.
